EDGE-SETTING- IRON.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed August 9, 1906. Serial No. 329,923.

To all whom it may concern:

Be it known that we, CHRISTIAN J oRGEN- sun, of Kronborggade No. 13, Copenhagen, in the Kingdom of Denmark, mechanical en gineer, and ANTON l-Lnunt, of H. P. Larsens Sidevej No. 5, Copenhagelt in the Kingdom of Denmark, mechanical engineer, both citi- Z6118 of the Kingdom of Denmark, have invented certain new and useful Improvements in Edge-Setting Irons; and We do hereby declare the following to be a full,-clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of the present invention is to provide an improved edge setting iron with Tools of this kind are used in the boot and shoe-manufacturing trade for the purpose of polishing (burning) the edge of the sole and simultaneously produce on foot-gear that is not welted an imitation of the st tch separating (fair-stitch imitation) such as may frequently be seen upon wellesewn boots and shoes. The tool may also be used-in the manufacturing of welted boots and shoes where the stitch separating is replaced'by fair-stitch imitation. In tools of the said kind hitherto used the axle of the impression-wheel is fixed firmly in the tool,

- and the operator can only in a very. deficient 1118111181 and by exerting a pressure on the tool, adjust the depth of the fair-stitchirnitation. This-drawback is obviated through the present invention by arranging the axleof the impression-wheel so as to be capable of being adjusted in the tool, thereby rendering it possible to make lighter or deeper impressions into the rand or welt, according to cir cumstances. Q

The invention is illustrated on the accompanying drawing, in which:

'Figure 1 shows a longitudinal section of the edge setting iron, and Fig. 2 a detail..

a designates an edge-setting iron, adapted to be fixed to an edgesetting machine, and having a smooth face '1) of suitable form for burnin the edgep of the shoe sole. A bearing sur ace 5 formed on the iron slopes backward from theburning face at substantially damaging the same.

'. right angles to the upper beveled face n ofthe shoe sole. Behind said face and parallel thereto is formed a'bore 0 connected with the 1 face I) through a short slot (i running parallel to the bore. A slide mounted within, the bore carries a screw 9 which projects through the slot (1, said screw having a conical head h on which is rotatably mounted an impression wheel h.

By moving the slide f in the bore the wheel may be adj usted. with relation to the burning surface 6 for the purpose of increasing or diminishing the depth of the impressions made by the wheel h. The wheel may be held in its adjusted position by a collar Zc formed on the screw and when the latter is screwed into the slide the collar, which extends over the slot, rests on the face I) and locks the slide in lace. The outer edge of the wheel h is preferably beveled as at g to prevent its teeth from coming into contact with the upper of the shoe.

. Before starting operation the slide f is adjusted in the bore, in such position that the teeth of the impression wheel will lie at a suitable distance from the surface I), and the screw is then turned to firmly lock the slide. Theedge setting iron can now be used in the usual manner. plane in which the impression-wheel rotates is at right angles with the sloping edge n of the 1projecting shoe sole so that the fairstitc1 imitation has the same depth at the In the iron illustrated, the

outer edge of the sole as it has near the up er.

The adjustment of the im ression-w eel does not affect its relation wit 1 the upper so that a careless adjustment can not in any Way damage'the upper. This is a very imortant feature as it is necessary in other irons of this class to cover the impressionwheel with a shield to prevent the warm wheel from touching the upper and thereby A shield not being necessary in the tool forming the subject of this invention, the impression-wheel can be operated in closer proximity to the upper t an heretofore and thus the fair-stitch imi tation can be applied closer to the upper.

We claim:'

An edge setting iron having a fixed burning face, an inclined bearin surface above said face, and a bore arallei to said surfaciand connected therewith by a slot, a slide in formed thereon to engage the bearing surfaceand lock the screw in position, and a wheel on. the screw havin a toothed'periphery to engage the upper ace of a shoe sole.

"' In testimony that we claim the foregoing .as our invention, we have signed our names in presence of two subscribing witnesses.
